I think all the romances in BioWare games are creepy. Seriously, you are in a position of authority over these people. They court martial people for such behaviour .

Am I the only one who doesn't flirt with ANY NPC?! .

P.S. The worst one was Ashley from ME1. I refused to have anything to do with her but when I transferred my character to ME2 it forced me to have had a relationship with her. So I then played the game as if she had borderline personality disorder and was inventing a relationship for attention. Quite enjoyable.
